AZ-TV Now All-Digital Channel 7.1 in Phoenix: What You Need To Know (And Do)

AZ-TV has switched to all-digital broadcasting in the Phoenix area on Channel 7.1, providing a crystal-clear signal not possible with analog (non-digital) technology.

Channel 27 has left the air forever. This was necessary to replace the analog transmitter with a new state-of-the art digital transmitter.

If you've been watching AZ-TV over the air (no cable, no satellite) in the Phoenix area on Channel 27, you'll need one of the following:

* A TV set with a built-in digital tuner. All new TVs sold in the U.S. since May, 2007 have digital tuners. If you've bought one since then, you've got what you need. * A cable connection. For this, you'd need to call Cox, Qwest, or the local cable provider for your area and subscribe. * A satellite connection. Again, a subscription, through DIRECTV or Dish Network. * A digital-to-analog converter box. This is a set-top box that will recieve digital signals and convert them so they can be watched on your existing analog (non-digital) TV.

OK. I auto-tuned my Sammy's ATSC tuner and it picked up KAZT on 7.1 and 7.2, both SD feeds of the same broadcast. RTN (Retro Television Network) A TV Land type network will be broadcast on 7.2http://en.wikipedia....evision_Network

No. I do not get any signal. It is listed as 27-1 in the OTA channel list. I am unsure why the HR20 is not picking it up because they are using channel 27 for it's DTV signal in Phoenix. It might have something to to with the ID tag sending 7.1 and 7.2

Well, I guess that makes me feel better - at least it's not just me. How do we get DirecTv to fix this though?

I'm still not sure that I understand where the problem lies and who needs to fix it:

CBS digital channel is actually on 17 but mapped to their analog channel - 5. We receive HD CBS on 5-1 on the HR20.

ABC digital channel is actually on 56 but mapped to their analog channel - 15. We receive HD ABC on 15-1 on the HR20.

NBC digital channel is actually on 36 but mapped to their analog channel - 12. We receive HD NBC on 12-1 on the HR20.

FOX digital channel is actually on 31 but mapped to their analog channel - 10. We receive HD FOX on 10-1 on the HR20.

PBS digital channel is actually on 29 but mapped to their analog channel - 8. We receive HD CBS on 8-1 on the HR20.

MYTV digital channel is actually on 26 but mapped to their analog channel - 45. We receive HD MYTV on 45-1 on the HR20.

CW digital channel is actually on 49 but mapped to their analog channel - 61. We receive HD CW on 61-1 on the HR20.

KTKV digital channel is actually on 24 but mapped to their analog channel - 3. We receive HD KTKV on 3-1 on the HR20.

Why wouldn't KAZTV (7/27) work the same way?

That is the problem, KAZT is mapping 27 to 7I can't remember what it called, but it is sent with the transmission so the ATSC tuner displays 5-1 for 17. Once in awhile it went off and I had to tune to the actual channel, 17-1 to watch 5-1 in HD when I had the SD TiVo hooked up to my Sammy and wanted to watch CSI in HD.EDIT: I found out that it is called PSIP, Program and System Information Protocol

When I channel search on my TiVo, I get 2 sets of results for 7.1 and 7.2. The KAZT-DT1 and KAZT-DT2 results in no reception. The KAZT-CD1 and KAZT-CD2 work. My DirecTV OTA receiver tries to find KAZT-DT1 and KAZT-DT2 without success. Does anyone understand the difference between the DT and CD types of digital broadcast?
